  • Page 6: Introduction

    2.1.2 Easy Installation and Configuration The RamSan-810 is easy to install on a SAN or directly attached to a server. Most system-level parameters can be set from the front panel, including the management IP address. Once the IP is set, then most configurations and monitoring should be done through the intuitive Web interface.

  • Page 7: Reliability

    Reliability The RamSan-810 is designed to offer superior reliability to other solid state disks. Its standard features include modular Flash memory, hot-swap power supplies, fail-over ports, and external alerts via SNMP. System Management Basic management operations, including manual shutdown and alerts, are available from the front panel screen.

  • Page 8: Reviewing Your Shipment

    Reviewing Your Shipment Unpacking Texas Memory Systems, Inc. ships the RamSan-810 with a packing list. Ensure that you have received all of the components listed. 1. Examine the external chassis for any damage that might have occurred during shipping. 2. Inspect the interface plate for any screws that might have loosened during shipping.

  • Page 9: Rack Mounting

    Rack mounting The RamSan-810 solid state disk (SSD) system is a 1U rack-mountable system. Texas Memory Systems, Inc. ships the system with the slides and equipment needed to install it into a standard 19” rack. Figure 2: RamSan-810 Back RamSan-810 User’s Manual - 5 - Texas Memory Systems, Inc.

  • Page 10: Connections

    8-Gb per second. Accounting for encoding and overhead, the 4-Gb/sec transfer rate allows data to be transmitted to the RamSan-810 at a half duplex rate of approximately 400 MB/s. Fibre Channel interfaces have separate read and write connections that allow a maximum data rate of twice the half-duplex rate.
  • Page 11 Many applications require storage bandwidth that exceeds what a single FC connection can provide. To accommodate this situation, we provide up to 4 FC ports per RamSan-810, each of which can supply the bandwidth described above. Using multiple Fibre Channel connections...

  • Page 12: Connecting The Fibre Channel Or Infiniband Ports

    Figure 3: Fibre Channel Locations Figure 3 shows the port layout for the RamSan-810. Each controller has two FC ports: A and B, on the left and right respectively. The FC ports on the system are capable of connecting to Point-to-Point (N-Port), Arbitrated Loop (NL-port), or Switched Fabric (F-Port) topologies at 2-Gb, 4-Gb, or 8-Gb speeds.

  • Page 13: Connecting To A Network

    As a best practice, connect each of the RamSan-810 power cords to separate circuits. Figure 5: RamSan-810 Power Supply Getting Started This chapter will guide you through setting up your RamSan-810. It is important to accomplish the following tasks to make your system usable: RamSan-810 User’s Manual - 9 - Texas Memory Systems, Inc.
